  Sorry for more bikeshedding, but afaik rpm based distros are
using the armv7hl identifier, so it could as well be

/lib/ld-linux-armv7hl.so.3

  Other variant could be

/armv7hl-linux/lib/ld.so.3

but that only if one wants to implement multiarch with sysroot
set to /armv7hl-linux, but that creates several other issues...
